Modulating Polaron Behavior in PM6 Blends with Nonfullerene and Fullerene Acceptors: The Importance of Singlet Energy Transfer

Advanced Materials Interfaces, EarlyView.
Transient absorption spectroscopy is employed to demonstrate that nonfullerene acceptors inhibit the formation of bound polaron pairs in conjugated polymers, which would otherwise undergo rapid relaxation back to the ground state. Instead, efficient energy transfer from the polymer to the non‐fullerene acceptor takes place, facilitating high charge ...

Coverage Contact Control of Benzoxazole‐Based SAMs to Enhance the Operational Performance of Perovskite Nanocrystal Light–Emitting Diodes

Advanced Materials Interfaces, EarlyView.
Self‐assembled monolayers (SAMs) as hole‐selective injecting contacts in CsPbBr₃ nanocrystal‐based PeLEDs demonstrate improved performance over PEDOT:PSS. Optimized SAM deposition techniques enable enhanced charge injection, resulting in PeLEDs with external quantum efficiencies (EQEs) up to 6.8% and increase of the operational stability.

Evaluating the Local Bandgap Across inxGa1‐xas Multiple Quantum Wells in a Metamorphic Laser via Low‐Loss EELS

Advanced Materials Interfaces, EarlyView.
This research explores local bandgap, composition, and strain variations across InxGa₁−xAs quantum wells within a metamorphic laser structure using high‐resolution scanning transmission electron microscopy (STEM) and low‐loss electron energy loss spectroscopy (EELS). Results reveal significant inhomogeneities, particularly near interfaces, with bandgap

Beta‐Lactoglobulin for Water‐Based and Tunable Nanostructure Templating of Printed Titania Thin Films: The Influence of pH Value and Protein Concentration

Advanced Materials Interfaces, EarlyView.
The synthesis route for the fabrication of nanostructured titania thin films focuses on water‐based solutions, abundant, nontoxic materials, and a highly scalable deposition technique. Using beta‐lactoglobulin enables tunable titania thin film templating and allows for different domain sizes, porosities, and morphologies.

Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices

Advanced Materials Interfaces, EarlyView.
This perspective explores colloidal metasurfaces composed of plasmonic and emitting nanoparticles assembled by laser interference lithography and template‐assisted self‐assembly methods. Precise design strategies achieve directional emission, low‐threshold lasing, and tunable photonic bandgaps.
